Description

Referring to
https://bugzilla.redhat.com/show_bug.cgi?id=708305
binaries compiled by PCC do not work in Fedora 15 (glibc 2.13.90). PCC works fine in Fedora 14 (glibc-2.13).
Example: A Hello World program (a.c)
#include <stdio.h>
int main()
{
printf("Hello\n");
return 0;
}
compiled with
$ pcc a.c
and run with
$ ./a.out
results in
Hello
in Fedora 14 x86_64, but
$ ./a.out
Segmentation fault (core dumped)
in Fedora 15.
Output of $valgrind ./a.out
